There was something today on www.traderbulletin.com that made me wonder. It says specialists are making less money even though their volume is increasing. If specialists are making less money on their principle trading, I'm guessing they're going to do anything they can to make more money from the order flow they've got. In other words, maybe the listed daytrader is about to get shaken down even more?

I don't know of any firms that do have an edge with openbook but who knows? There are a few firms that have a huge edge on nasdaq because the software they are using allows them to see the contra party trades for every share traded on a particular ecn.

That is prettty nice thing to have because you can have goldman on the offer but if you are seeing him buy shares off the ecn you know he is just holding down the stock while he accumulates shares before it eventually goes and visa versa.
